Matej Jelluš
IT Nerd & Fractional CTO
I help Startups and Scaleups to build and scale their products and engineering teams.
Architecture
Experience from various projects, which are used by thousands of clients around the world, made me plan and predict in advance and forsee possible problems before they actually happen.
Engineering team
Leading a team towards goals and helping them grow is something I have been doing for several years now.
Idea
Talking about ideas and validating them is fun and in the same time it moves you forward. I am more "it can be done" than "it is impossible" person.
Cloud Native & AWS
Analyzing the current application architecture and business requirements for a better understanding of overall functionality. Proposing changes to ensure greater stability, scalability, and maintainability. Reviewing infrastructure expenses and exploring opportunities for cost savings.
Training developers to utilize cloud services whenever possible and save time when implementing new features. This often solves more than one problem and makes the application more robust.
Technical Guidance
This is a broad topic and depends on your specific needs. It can cover areas like building minimum viable product, time to market, or build vs buy decision. In later stages it also includes tehcnical leadership, hiring and firing, or talent retention.
At the same time, it can be more technical. Many developers or development teams need (or want) to validate their solution with someone else before development starts. They want to ensure that the proposed solution is optimal and that there are no other easier, better, or faster alternatives.

Unfortunatelly both Podcast and YouTube video are in Slovak language.
